Cylindrical vs. box shaped subwoofers

Not exactly rocket science. Get a bunch of 2x2 clear pine, some 3 1/2" dry wall screws, a 1/8" drill, and some construction adhesive. Onw of the real big problems with these concrete forms is that they are wax-coated (first to prevent water from soaking in to them when they're filled with concrete, secondly to make it easy to strip them off once they're done. The wax coating makes the use of any adhesive-based solution a real challenge. Friends who have done projects with them tell me that scrubbing with petroleum distillates solves that problem when it exists. Possibly, there is some other brand of tubing that would be thicker and possibly more rigid. If you're so committed to marrying these things, what's wrong with the idea of taking two forms of somewhat different diameter and filling the space between them with sand? Now that would be a robust and very acoustically dead solution, not to mention very heavy. |
